Except for Akok, Gaffney and Bouknight. It's a dumb pissing contest in any event. Nobody really closely connected to the team would be able to reveal details showing those connections or those connections would dry up. I take everything from everyone with several spoonfuls of salt.
If Precious comes here, what does that mean for Zion's "Next"? Is he a fraud then? No. It means that Dan Hurley himself can't predict what these kids will do with any certainty, nor could Ollie or Calhoun. The most we can get from any insider is a vague sense of what the staff thinks, which may or may not be accurate itself.
